1. Hlavn\u00e1 \u0161trukt\u00fara
\nHlavn\u00e1 kon\u0161trukcia vrtnej plo\u0161iny pozost\u00e1va z trupu, most\u00edka, zdv\u00edhacieho syst\u00e9mu, syst\u00e9mu horizont\u00e1lnej stability, rozvodu energie a riadiaceho syst\u00e9mu at\u010f.
\nTrup je z\u00e1kladom vrtnej plo\u0161iny a nesie v\u0161etky za\u0165a\u017eenia vrtnej plo\u0161iny. Most je most\u00edk sp\u00e1jaj\u00faci trup a vrtn\u00fa ve\u017eu, ktor\u00fd nesie a pren\u00e1\u0161a za\u0165a\u017eenie vrtnej ve\u017ee.

\n2. \u0160trukt\u00fara v\u00fd\u0165ahu
\nKon\u0161trukcia ve\u017ee je najd\u00f4le\u017eitej\u0161ou \u010das\u0165ou vrtnej plo\u0161iny. V\u0155tacie zariadenie je nain\u0161talovan\u00e9 na ve\u017ei a v\u0155tacia ty\u010d sa posiela do vrtu cez ve\u017eu na v\u0155tacie pr\u00e1ce.
\nKon\u0161trukcia vrtnej ve\u017ee pozost\u00e1va zo st\u013apov, nosn\u00edkov, diagon\u00e1lnych v\u00fdstuh, z\u00e1vesn\u00fdch most\u00edkov, z\u00e1bradl\u00ed, plo\u0161\u00edn a podl\u00e1h, ktor\u00e9 navz\u00e1jom spolupracuj\u00fa pri vykon\u00e1van\u00ed v\u0155tania.

Podlaha poskytuje pohodlnej\u0161ie funkcie, ako je riadenie na mieste a \u0161kolenie o \u00fadajoch.
\n3. V\u0155tacie zariadenie
\nV\u0155tacie zariadenie je z\u00e1kladnou s\u00fa\u010das\u0165ou vrtnej plo\u0161iny, vr\u00e1tane vrtn\u00fdch s\u00faprav, vrtn\u00fdch r\u00far, vrtn\u00fdch vrt\u00e1kov, \u0165a\u017eobn\u00e9ho zariadenia, zariadenia na cirkul\u00e1ciu bahna at\u010f. Vrtn\u00e1 s\u00faprava je hlavn\u00fdm zariaden\u00edm na dokon\u010denie vrtn\u00fdch pr\u00e1c a m\u00f4\u017ee dokon\u010di\u0165 r\u00f4zne vrtn\u00e9 pr\u00e1ce pod\u013ea r\u00f4znych konfigur\u00e1ci\u00ed a po\u017eiadaviek. V\u0155tacia r\u00fara je d\u00f4le\u017eitou s\u00fa\u010das\u0165ou spojenia vrt\u00e1ka a vrtnej s\u00fapravy.

\n4. Pomocn\u00e9 zariadenia
\nOkrem uveden\u00fdch hlavn\u00fdch \u010dast\u00ed a vrtn\u00e9ho zariadenia je vrtn\u00e1 plo\u0161ina vybaven\u00e1 aj radom pomocn\u00fdch zariaden\u00ed vr\u00e1tane obytn\u00fdch priestorov, zariaden\u00ed na z\u00e1sobovanie energiou, sanit\u00e1rnych zariaden\u00ed, jed\u00e1ln\u00ed, skladov, kancel\u00e1ri\u00ed at\u010f. Tieto zariadenia m\u00f4\u017eu poskytn\u00fa\u0165 potrebn\u00e9 \u017eivotn\u00e9 a pracovn\u00e9 podmienky pre person\u00e1l vrtnej plo\u0161iny a zabezpe\u010di\u0165 bezpe\u010dnos\u0165 a efektivitu pr\u00e1ce person\u00e1lu.<\/p>\n

Pri rozvoji morsk\u00fdch zdrojov ropy a zemn\u00e9ho plynu existuje druh zariadenia, o ktorom mo\u017eno poveda\u0165, \u017ee k nemu nevyhnutne prispieva, a to vrtn\u00e1 plo\u0161ina na mori. Medzi morsk\u00e9 vrtn\u00e9 plo\u0161iny zvy\u010dajne patria plo\u0161iny umiestnen\u00e9 na dne, plo\u0161iny so zdvih\u00e1kom, vrtn\u00e9 lode, FPSO, poloponorn\u00e9 plo\u0161iny, pl\u00e1\u0161\u0165ov\u00e9 plo\u0161iny, bet\u00f3nov\u00e9 gravita\u010dn\u00e9 plo\u0161iny, hlbokovodn\u00e9 ve\u017eov\u00e9 plo\u0161iny at\u010f. S cie\u013eom uspokoji\u0165 potreby hlbinn\u00e9ho v\u0155tania a v\u00fdvoja sa objavili hlbinn\u00e9 konzolov\u00e9 plo\u0161iny, ako s\u00fa plo\u0161iny s napnut\u00fdmi nohami (TLP) a jednoko\u013eajov\u00e9 plo\u0161iny (SPAR).<\/p>\n

Medzi plytkovodn\u00e9 vrtn\u00e9 plo\u0161iny v s\u00fa\u010dasnosti patria najm\u00e4 pl\u00e1\u0161\u0165ov\u00e9 plo\u0161iny (pevn\u00e9) a mobiln\u00e9 plo\u0161iny typu jack-up. Maxim\u00e1lna prev\u00e1dzkov\u00e1 h\u013abka pl\u00e1\u0161\u0165ovej plo\u0161iny m\u00f4\u017ee dosiahnu\u0165 \u0161tyristo a\u017e p\u00e4\u0165sto metrov, ale ke\u010f sa zmen\u00ed poloha ropn\u00e9ho po\u013ea, prisp\u00f4sobivos\u0165 plo\u0161iny je nedostato\u010dn\u00e1. Najroz\u0161\u00edrenej\u0161\u00edmi plo\u0161inami sa stali plo\u0161iny Jack-up, preto\u017ee sa m\u00f4\u017eu flexibilne kr\u010di\u0165 a st\u00e1\u0165 v morsk\u00fdch oblastiach v h\u013abke do 200 metrov a maj\u00fa dobr\u00fa stabilitu.
\nVrtn\u00e9 plo\u0161iny Jack-up sa skladaj\u00fa z plo\u0161\u00edn, pil\u00f3t a zdv\u00edhac\u00edch mechanizmov. Plo\u0161inu mo\u017eno zdv\u00edha\u0165 a sp\u00fa\u0161\u0165a\u0165 pozd\u013a\u017e pil\u00f3t a spravidla nem\u00e1 schopnos\u0165 vlastn\u00e9ho pohonu. Po\u010das prev\u00e1dzky sa pil\u00f3tov\u00e9 nohy sp\u00fa\u0161\u0165aj\u00fa a zas\u00favaj\u00fa do morsk\u00e9ho dna, plo\u0161ina sa zdv\u00edha do bezpe\u010dnej pracovnej v\u00fd\u0161ky od morskej hladiny a pil\u00f3tov\u00e9 nohy s\u00fa vopred stla\u010den\u00e9, aby sa zabezpe\u010dilo, \u017ee sa pil\u00f3tov\u00e9 nohy nepotopia, ke\u010f sa plo\u0161ina dostane do b\u00farky. Po dokon\u010den\u00ed vrtu sa plo\u0161ina spust\u00ed na morsk\u00fa hladinu, pil\u00f3tov\u00e9 nohy sa vytiahnu a \u00faplne zdvihn\u00fa, cel\u00e1 plo\u0161ina pl\u00e1va na morskej hladine a remork\u00e9r ju odtiahne na nov\u00e9 miesto vrtu.
\nPracovn\u00e9 kroky samozdv\u00edhacej platformy na mori
\nSamozdv\u00edhacia v\u0155tacia plo\u0161ina sa sklad\u00e1 z troch \u010dast\u00ed: v\u0155tacieho modulu, modulu trupu a zdv\u00edhacieho modulu. V\u0155tac\u00ed modul sa sklad\u00e1 z r\u00f4znych prev\u00e1dzkov\u00fdch strojov; modul trupu je podobn\u00fd \u010dlnu, ktor\u00fd sa pou\u017e\u00edva na prepravu v\u0155tacieho modulu a obytn\u00fdch priestorov. Zdv\u00edhac\u00ed modul je zodpovedn\u00fd najm\u00e4 za zdv\u00edhanie a sp\u00fa\u0161\u0165anie plo\u0161iny, zvy\u010dajne sa naz\u00fdva aj zdv\u00edhac\u00ed syst\u00e9m, a jeho hlavnou s\u00fa\u010das\u0165ou s\u00fa pil\u00f3tov\u00e9 nohy.
\nLaicky povedan\u00e9, samozdv\u00edhacia vrtn\u00e1 plo\u0161ina je funk\u010dn\u00e1 plo\u0161ina so schopnos\u0165ou samozdv\u00edhania. V\u00fd\u0161kov\u00e9 zmeny dosahuje prostredn\u00edctvom pil\u00f3tov\u00fdch n\u00f4h ur\u010ditej d\u013a\u017eky, ktor\u00e9 sa m\u00f4\u017eu sam\u00e9 zdv\u00edha\u0165 a sp\u00fa\u0161\u0165a\u0165, aby sa prisp\u00f4sobili po\u017eiadavk\u00e1m r\u00f4znych prev\u00e1dzkov\u00fdch h\u013abok vody.

Prev\u00e1dzkov\u00e1 h\u013abka vody je preto \u00fazkym miestom vrtnej plo\u0161iny typu jack-up. V s\u00fa\u010dasnosti je jej prev\u00e1dzkov\u00fd rozsah obmedzen\u00fd na 200 m h\u013abky vody kontinent\u00e1lneho \u0161elfu.
